For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0049] In the embodiments of the present invention, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0050] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model embodiment. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0051] Heat pump water heaters, also known as "air source heat pump water heaters" and "air energy water heaters", absorb low-temperature heat from the air, gasify the refrigerant in the evaporator, and turn it into low-temperature steam. The low-temperature steam is then compressed by a compressor and converted into high-temperature, high-pressure gas, and then the compressed high-temperature heat is converted into water heating by a heat exchanger. Therefore, compared with traditional electric water heaters and gas water heaters, heat pump water heaters have many advantages such as high efficiency, energy saving, environmental protection, and safety.

[0052] During the operation of the heat pump water heater, long-term excessive use or frequent start-stopping may cause fatigue damage to the air duct, or damage due to aging of the material of the air duct. In addition, dust and dirt may accumulate in the air duct, causing blockage or affecting its normal operation. Therefore, the air duct needs to be regularly inspected or repaired. However, when repairing or inspecting the air duct of the heat pump water heater in the prior art, the outer shell needs to be removed first, and then the air duct is disassembled, which is inconvenient and requires a lot of time and effort.

[0053] See also Figures 1 to 2 In a first aspect, an embodiment of the utility model provides a head assembly of a heat pump water heater, including a base 100 and an air duct 200 . The air duct 200 is detachably connected to the base 100 , and a disassembly hole 111 of the air duct 200 is formed on the base 100 .

[0054] The air duct 200 is detachably connected to the base 100, and the air duct 200 can be removed from the base 100 separately, so that the air duct 200 can be inspected and repaired separately. The base 100 is formed with a disassembly hole 111 of the air duct 200, and the air duct 200 can be installed and removed through the disassembly hole 111 of the base 100 without disassembling the whole machine.

[0055] It is understandable that the air duct 200, as a part of the air supply system of the heat pump water heater, is easily damaged due to long-term use or material aging. The air duct 200 may accumulate dust, dirt, etc. and requires regular maintenance. The disassembly hole 111 of the air duct 200 can be used to carry out targeted maintenance or regular inspections of the air duct 200 to improve the safety of the heat pump water heater. Furthermore, the disassembly hole 111 is provided on the base 100, which is easier to hide and does not affect the overall appearance.

[0056] It can be understood that, generally, the base 100 is a base, the inner tank of the water heater is arranged at the upper end of the head assembly, and a disassembly hole 111 is opened at the lower end of the base to realize the disassembly of the air duct 200 from the lower end of the base; the base 100 can also be a top seat, the inner tank of the water heater is arranged at the lower end of the head assembly, and a disassembly hole 111 is opened at the upper end of the top seat to realize the disassembly of the air duct 200 from the upper end of the top seat; or, in some embodiments, the base 100 can also have a side wall, and the disassembly hole 111 is arranged on the side wall. Regardless of whether the inner tank of the water heater is arranged at the upper end or the lower end of the head assembly, the air duct 200 can be disassembled.

[0057] In one embodiment, the air duct 200 may be in the shape of a curved tube, for example, see Figure 1 and Figure 3 , an air inlet channel 240 and an air outlet channel 250 are formed inside the air duct 200, the airflow of the air inlet channel 240 flows horizontally, and the airflow of the air outlet channel 250 flows vertically; the wind flowing horizontally enters the air inlet channel 240 and is blown out by the air outlet channel 250. Since the airflow of the air inlet channel 240 flows horizontally and the airflow of the air outlet channel 250 flows vertically, the airflow flowing horizontally is converted into vertical flow; correspondingly, the base 100 can be provided with an exhaust port 130, and the air outlet 251 of the air outlet channel 250 faces the exhaust port 130 to guide the wind to the exhaust port 130 of the base 100, realize the change of the wind flow direction, and avoid the horizontally flowing wind directly discharged from the water heater to cause damage to the wall. In addition, the curved pipe design can be more effectively laid out in a limited space and reduce the noise and vibration of the heat pump water heater. Alternatively, the air duct 200 can also be a straight pipe to simplify the structure, and the air duct 200 only needs to be disassembled and installed from the disassembly hole 111. In addition, the cross section of the air duct 200 may be circular or square.

[0058] The utility model provides a head assembly of a heat pump water heater, such as Figure 1 and Figure 4 As shown, it also includes a fan 300 and a fan bracket 400 , the fan 300 is installed on the fan bracket 400 , and the fan bracket 400 is installed on the base 100 ; the air duct 200 is detachably installed on the fan bracket 400 .

[0059] The fan bracket 400 is used to fix the fan 300, and the air duct 200 can be detachably mounted on the fan bracket 400. When the air duct 200 is disassembled or assembled, the air duct 200 can be removed or assembled separately. Among them, "the air duct 200 can be detachably mounted on the fan bracket 400" includes the situation that the air duct 200 and the fan bracket 400 are not directly connected. In this case, the air duct 200 can be fixed on the base 100 or other fixed objects, and the air inlet of the air duct 200 only needs to face the fan 300.

[0060] In one embodiment, when the fan 300 is inspected and repaired, the fan bracket 400 may be disassembled and assembled separately, and the fan bracket 400 may be disassembled without disassembling the air duct 200 .

[0061] In one embodiment, the fan bracket 400 can be detachably mounted on the base 100. When the fan 300 needs to be disassembled, the fan bracket 400 can be directly disassembled. There is no need to disassemble the fan 300 separately, so as to avoid the screws and other fixings that fix the fan 300 from loosening after multiple disassembly and assembly, thereby affecting the normal operation of the fan 300. After the fan bracket 400 is disassembled, the fan bracket 400 still serves as a support for the fan 300, and the fan 300 can be directly repaired or inspected on the fan bracket 400. At the same time, due to the supporting function of the fan bracket 400, the fan 300 can be directly placed on a table or on the ground for repair, which is convenient for operation; furthermore, during the disassembly process, the fan 300 will not be directly operated, so as to avoid damage to the fan 300 during the disassembly process.

[0062] See also Figures 3 to 5 In one embodiment, the fan bracket 400 includes a bracket body 410 and an assembling plate 420; the assembling plate 420 is fixed to the side of the bracket body 410 facing the air duct 200; an avoidance gap 210 is provided at the top of the air duct 200, and the avoidance gap 210 is used to avoid the fan 300 when disassembling and assembling the air duct 200; when the air duct 200 is fixed to the bracket body 410, the assembling plate 420 is assembled in the avoidance gap 210.

[0063] In order to better introduce wind into the air duct 200, the blades of the fan 300 at least partially extend into the air duct 200. Since the disassembly hole 111 is set on the base 100, when removing the air duct 200, it is necessary to take it out from top to bottom. Therefore, an avoidance gap 210 is set at the top of the air duct 200. When removing the air duct 200, the blades of the fan 300 can pass through the avoidance gap 210 to prevent the fan 300 from obstructing the disassembly work of the air duct 200.

[0064] When the air duct 200 is fixed to the bracket body 410 , the assembly plate 420 is assembled in the avoidance gap 210 . The assembly plate 420 connects the air duct 200 and appropriately extends the air duct 200 .

[0065] See also Figure 1 and Figure 2 In one embodiment, the base 100 includes a base body 110 and a base body cover 120 , a disassembly hole 111 is formed in the base body 110 , and the base body cover 120 can be detachably installed in the disassembly hole 111 .

[0066] The seat cover 120 can be detachably mounted on the disassembly hole 111, and the seat cover 120 can realize the opening and closing of the disassembly hole 111; the shape of the seat cover 120 can match the disassembly hole 111 so as to close the disassembly hole 111; the shape of the seat cover 120 can also not match the disassembly hole 111, and the disassembly hole 111 can be opened and closed by disassembling the seat cover 120; the seat cover 120 can be directly connected to the base or indirectly connected to the base, for example, the seat cover 120 can be installed on the fan bracket 400. Alternatively, in some embodiments, the seat cover 120 can be rotatably connected to the base 110, and the disassembly hole 111 can be opened and closed by rotating the seat cover 120.

[0067] In one embodiment, a disassembly notch 112 is formed on the base 110, and the disassembly notch 112 is located above the base cover 120. When disassembling the base cover 120, one only needs to put a finger on the disassembly notch 112 and pry the base cover 120 to complete the disassembly.

[0068] It is understandable that the disassembly notch 112 may be connected to the disassembly hole 111 to facilitate processing; the disassembly notch 112 may also not be connected to the disassembly hole 111 and only needs to be located above the seat cover 120 .

[0069] See also Figure 3 and Figure 5 In one embodiment, first buckles 421 are provided at both ends of the assembly plate 420 , and second buckles 220 are provided at both sides of the air duct 200 corresponding to the avoidance gap 210 , and the first buckle 421 and the second buckle 220 cooperate with each other.

[0070] The cooperation of the first clip 421 and the second clip 220 facilitates the assembly and disassembly of the air duct 200 and the fan bracket 400. The air duct 200 is taken out from the disassembly hole 111, and the first clip 421 and the second clip 220 are disengaged, so that the air duct 200 can be removed without removing the entire fan 300 and the air duct 200 together. The first buckle 421 is a clip arranged on the assembly plate 420, and a gap is formed between the clip and the assembly plate 420. The second buckle 220 is a protrusion. When the air duct 200 is installed, the side wall of the air duct 200 corresponding to the avoidance notch 210 is inserted into the gap between the clip and the assembly plate 420, and the protrusion opens the gap to fix the air duct 200. The surface of the protrusion is arc-shaped, and correspondingly, the end of the clip is arc-shaped, which is convenient for insertion. The first buckle 421 can also be two clips arranged opposite to each other, and a gap is formed between the two clips. Of course, the first buckle 421 can also be arranged on the top plate 430. The air duct 200 and the fan bracket 400 can also be connected by means of threaded connection or the like.

[0071] See also Figure 3 and Figure 5 In one embodiment, the fan support 400 further includes a top plate 430, which is located above the assembly plate 420. When the assembly plate 420 is assembled in the avoidance gap 210, the top plate 430 overlaps the assembly gap to prevent air leakage. When the assembly plate 420 is assembled in the avoidance gap 210, the top plate 430 plays a limiting role, so that the air duct 200 is installed in the correct position. The top plate 430 is a shape that matches the air duct 200. If the air duct 200 is a square air duct 200, a groove can be set at the lower end of the top plate 430 to match the shape of the air duct 200. If the air duct 200 is a circular air duct 200, the top plate 430 can be a corresponding arc shape to fit the air duct 200.

[0072] See also Figure 3 and Figure 6 In one embodiment, a connecting component 230 is provided on the side of the air duct 200 facing the fan bracket 400, and the connecting component 230 is provided with a mounting portion 231, and the mounting portion 231 is provided corresponding to the bottom surface of the base 100, and is used to fix the air duct 200 to the base 100. It is convenient to install and fix the air duct 200 from the bottom of the base 100; a fixing groove can be provided on the mounting portion 231, and a fixing protrusion can be provided at a corresponding position of the base 100, and the air duct 200 can be fixed on the base 100 through the cooperation of the fixing protrusion and the fixing groove; a through hole can also be provided on the mounting portion 231, and a threaded hole can be provided correspondingly on the base 100. The embodiment of the utility model can also include a fastening screw, and the fastening screw passes through the through hole and the threaded hole in sequence to achieve the connection effect.

[0073] See also Figure 3 and Figure 6In one embodiment, a column 500 is fixed on the base 100, one of the connecting member 230 and the column 500 is provided with a duct guide rail 232, and the other is provided with a duct guide groove, and the duct guide rail 232 is slidably arranged on the duct guide groove. The duct guide rail 232 is slidably arranged on the duct guide rail 232; through the cooperation between the duct guide rail 232 and the duct guide rail 232, the installation error can be reduced, the installation accuracy can be improved, and the installation position of the duct 200 and the fixing of the duct 200 can be more easily determined during the installation process, the stability of the installation is ensured, and the disassembly and installation are easier.

[0074] See also Figures 4 to 5 In one embodiment, the fan bracket 400 includes a lower bracket 411 and an upper bracket 412, the upper bracket 412 is formed with a first assembling surface 4121 and a second assembling surface 4122, the first assembling surface 4121 is in contact with the upper end surface of the lower bracket 411, and the second assembling surface 4122 is in contact with the upper end surface of the connecting component 230.

[0075] It can be understood that the first assembling surface 4121 is fitted with the upper end surface of the lower bracket 411, and the second assembling surface 4122 is fitted with the upper end surface of the connecting component 230 to support the upper bracket 412. Through the surface contact between the first assembling surface 4121 and the upper end surface of the lower bracket 411 and the surface contact between the second assembling surface 4122 and the upper end surface of the connecting component 230, the pressure of the upper bracket 412 can be more evenly dispersed, reducing the possibility of local stress concentration. The upper bracket 412 is provided with a first recess on a side away from the assembling plate 420, and the lower bracket 411 is provided with a second recess corresponding to the first recess. The first recess and the second recess are connected to form a fan 300 opening, and the fan 300 opening is connected to the air inlet of the air duct 200. The fan 300 is installed on the fan bracket 400, and the fan 300 extends into the fan 300 opening to facilitate the introduction of wind into the air duct 200; the first recess can be flush with the assembling plate 420 to avoid obstructing the flow of wind.

[0076] See also Figure 5 In one embodiment, one of the fan bracket 400 and the column 500 is provided with a bracket guide rail 4123, and the other is provided with a bracket guide groove, and the bracket guide rail 4123 is slidably arranged in the bracket guide groove. Through the cooperation of the bracket guide rail 4123 and the bracket guide rail 4123, the installation error can be reduced and the installation accuracy can be improved. The bracket guide rail 4123 can be provided on the upper bracket 412, and the bracket guide groove can be provided on the column 500. During the installation process, it is easier to determine the installation position of the upper bracket 412 and fix the upper bracket 412, ensure the stability of the installation, and make it easier to disassemble and install.

[0077] To facilitate installation, a bracket guide groove and an air duct guide groove may be provided on the column 500, an air duct guide rail 232 may be provided on the connecting component 230 of the air duct 200, and bracket guide rails 4123 may be provided on both sides of the upper bracket 412; the bracket guide groove and the air duct guide groove may be connected to facilitate processing and facilitate the fitting of the second assembly surface 4122 and the upper end surface of the connecting component 230.

[0078] See also Figure 3 In one embodiment, the air duct 200 forms an avoidance groove 260 on a side facing away from the fan bracket 400, and the avoidance groove 260 is used to avoid internal parts of the heat pump water heater.

[0079] See also Figures 1 to 7 The head assembly of the heat pump water heater includes an upper cover 600 and a surrounding plate 700 located above the base. The surrounding plate 700 is arranged between the base and the upper cover 600 to form an installation space 710. The interior of the installation space 710 is provided with a compressor 810, an evaporator 820, an electric control box 830 and many other internal parts; an avoidance groove 260 is arranged on the air duct 200, which can effectively layout the installation space 710 and coordinate the relationship between various internal parts; for example, a capacitor is protruded from the surface of the electric control box 830, and the capacitor of the electric control box 830 is arranged toward the air duct 200. The avoidance groove 260 can avoid the capacitor and use part of the space of the air duct 200. The electric control box 830 can be installed without expanding the heat pump water heater.

[0080] The air duct 200 can be set in the middle of the base, and the internal parts such as the compressor 810, the evaporator 820, and the electrical control box 830 are set on the surrounding side of the air duct 200. If the size of the installation space 710 is not sufficient to accommodate other internal parts, an avoidance groove 260 can be set at the corresponding position of the air duct 200 to coordinate the installation of other internal parts.

[0081] In addition, the avoidance groove 260 can be connected to the top of the air duct 200 to avoid hindering the air duct 200 from being removed from the disassembly hole 111 of the base from top to bottom.
